| 1 | The revival of thermal utilization from the Sun: interfacial solar vapor generation显示文摘Since solar energy is the ultimate energy resource and a significant amount of global energy utilization goes through heat,there have been persistent efforts for centuries to develop devices and systems for solar–thermal conversion.Most recently,interfacial solar vapor generation,as an emerging concept of solar–thermal conversion,has gained significant attention for its great potentials in various fields such as desalination,sterilization,catalysis,etc.With the advances of rationally designed materials and structures and photon and thermal management at the nanoscale,interfacial solar vapor generation has demonstrated both thermodynamic and kinetical advantages over conventional strategies.In this review,we aim to illustrate the definition,mechanism and figures of merit of interfacial solar vapor generation,and to summarize the development progress of relevant materials and applications,as well as to provide a prospective view of the future. | Lin Zhou Xiuqiang Li George W.

| 2 | Effect of different concentrations of surfactant on the wettability of coal by molecular dynamics simulation显示文摘Anionic surfactant sodium dodecyl benzene sulfonate(SDBS)at varying concentrations was selected to investigate the influence on the wettability of Zhaozhuang Coal by molecular dynamics simulation.Six groups of water/surfactant/coal systems with different concentrations were constructed.The influence of surfactant with different concentrations on the wettability of coal was concluded by analyzing various properties from the energetic behaviors to the dynamic characteristics.The results show that the interfacial tension decreases sharply and then rises slowly with the increase of SDBS surfactant concentration,obtaining that surfactants can obviously reduce the interfacial tension.The surfactant molecules could be detected at the water/coal interface through analyzing the system’s relative concentration distribution.In addition,the difference in the wettability of surfactants on coal surfaces is caused by the spatial distribution differences of alkyl chains and the benzene ring of the surfactant molecules.And the negative interaction energy between SDBS and the coal surface indicates that adsorption process is spontaneous.Furthermore,it is of great practical significance for improving the dust reduction effect and reducing the disaster of coal dust by exploring the effects of surfactant molecules on the wettability of coal. | Junqing Meng Feifei Yin Shichao Li Ruquan Zhong Zeyuan Sheng Baisheng Nie | 2019 | International Journal of Mining Science and Technology2019，29，4： | 20 |
| 3 | Recent advances in joining of SiC-based materials(monolithic SiC and SiC_f/SiC composites):Joining processes,joint strength, and interfacial behavior显示文摘Silicon carbide(SiC) has been widely concerned for its excellent overall mechanical and physical properties, such as low density, good thermal-shock behavior, high temperature oxidation resistance, and radiation resistance; as a result, the SiC-based materials have been or are being widely used in most advanced fields involving aerospace, aviation, military, and nuclear power. Joining of SiC-based materials(monolithic SiC and SiCf/SiC composites) can resolve the problems on poor processing performance and difficulty of fabrication of large-sized and complex-shaped components to a certain extent, which are originated from their high inherent brittleness and low impact toughness.Starting from the introduction to SiC-based materials, joining of ceramics, and joint strength characterization, the joining of SiC-based materials is reviewed by classifying the as-received interlayer materials, involving no interlayer, metallic, glass-ceramic, and organic interlayers. In particular, joining processes(involving joining techniques and parameter conditions), joint strength,interfacial microstructures, and/or reaction products are highlighted for understanding interfacial behavior and for supporting development of application-oriented joining techniques. | Guiwu LIU Xiangzhao ZHANG Jian YANG Gunjun QIAO | 2019 | Journal of Advanced Ceramics2019，8，1： | 14 |
| 4 | Review on application of nanoparticles for EOR purposes: A critical review of the opportunities and challenges显示文摘Nanoparticles have already gained attentions for their countless potential applications in enhanced oil recovery.Nano-sized particles would help to recover trapped oil by several mechanisms including interfacial tension reduction, impulsive emulsion formation and wettability alteration of porous media. The presence of dispersed nanoparticles in injected fluids would enhance the recovery process through their movement towards oil–water interface. This would cause the interfacial tension to be reduced. In this research, the effects of different types of nanoparticles and different nanoparticle concentrations on EOR processes were investigated. Different flooding experiments were investigated to reveal enhancing oil recovery mechanisms. The results showed that nanoparticles have the ability to reduce the IFT as well as contact angle, making the solid surface to more water wet. As nanoparticle concentration increases more trapped oil was produced mainly due to wettability alteration to water wet and IFT reduction. However, pore blockage was also observed due to adsorption of nanoparticles, a phenomenon which caused the injection pressure to increase. Nonetheless, such higher injection pressure could displace some trapped oil in the small pore channels out of the model. The investigated results gave a clear indication that the EOR potential of nanoparticle fluid is significant. | Yousef Kazemzadeh Sanaz Shojaei Masoud Riazi Mohammad Sharifi | 2019 | Chinese Journal of Chemical Engineering2019，27，2： | 12 |
| 5 | Mesomechanism of steel fiber reinforcement and toughening of reactive powder concrete显示文摘Reactive powder concrete (RPC) is a novel cement-based composite material with ultra-high strength. Embedding a certain amount of short steel fibers in the matrix can improve the RPC’s toughness and overcome the disadvantage of high brittle- ness. In this paper, a number of direct uniaxial tension tests have been carried out with ‘8-shape’ RPC200 specimens. The bond-slip process, mesoscopic structural variation and mechanical characteristics of a fiber pullout of the matrix have been investigated using the real-time SEM loading system and CCD observation tech- niques. The influence of the volume of embedded short steel fibers in matrix on the mesoscopic morphology of attachments on the surface of a pulled individual fiber, the initial cracking force, the ultimate pullout force, interfacial bond strength and the pullout rupture energy have been analyzed. A general formulation relating these quantities to the volume of fibers in matrix has been proposed. The components comprising the interfacial bond strength have been outlined. In addition, the con- tribution that fibers make to enhance and toughen the reactive powder concrete has been discussed. It is shown that there exists an optimal threshold of fiber volume ρv, opt =1.5% at which the bond performance of a fiber pullout of RPC be- haves best. | JU Yang JIA YuDan LIU HongBin CHEN Jian | 2007 | Science China(Technological Sciences)2007，50，6： | 9 |
| 6 | On the boundary slip of fluid flow显示文摘This paper presents a stress controlled boundary slip model and predicts the fluid-solid interface slip in a system of parallel sliding plates or a sphere approaching a smooth plane. The numerical simulation results are in striking agreement with the existing experimental observations. This model assumes that there is a limiting shear stress. No slip occurs if the surface shear stress is smaller than the limiting shear stress, and slip occurs when the surface shear stress equals it. It is found that boundary slip dramatically decreases the hydrodynamic pressure if the two squeezed surfaces have the same slip property. Finally, the hydrodynamic force reaches a saturation status and almost does not decrease any more. Compared with the no-slip solution, hydrodynamic force is found to decrease by over two orders in the case of boundary slip. When the squeezed surfaces have different slip properties, however, the hydrodynamic pressure is mainly controlled by the surface having a smaller surface limiting shear stress, and reduces more slowly compared with the case of two surfaces having the same slip property. Even when one of the surfaces has a zero surface limiting shear stress, a considerable hydrodynamic force still exists. | WU Chengwei MA Guojun | 2005 | Science China(Physics,Mechanics & Astronomy)2005，48，2： | 8 |
| 7 | PHYSICAL SIMULATION OF INTERFACIAL CONDITIONS IN HOT FORMING OF STEELS显示文摘In the last few years,substantial experimental simulation and mumerical modelling hare been carried out in IMMPETUS to characterise the interfacial heat transfer and friction conditions during hot forging and rolling of steels. Emphasis has been placed on the influence of the oxide scale which forms on the steel workpiece. In the present paper, the experimental methods used for investigating interfacial heat transfer and friction conditions are described. Theses include hot flat rolling of steel slabs and hot axi- symmetric forging of steel cylinders and rings.Temperature measurements and computations demon- strate that for similar conditions, similar conditions, the effective interfacial heat transfer coefficients (IHTC) derived for hot rolling are significantly higher than those for forging, mainly due to the contribution of scale cracking during rolling. On the basis of experimental observations and numerical analysis,physical models for interfacial heat transfer in forging and rolling have been established. In addition, hot' sandwich' rolling and hot tensile tests with finite element modelling have been carried out to evaluate the hot ductility of the oxide scale.The results indicate that the defomation, cracking and decohesion behaviour of the oxide scale depend on deformation temperature, strain and relative strengths of the scale layer and scale - steel interface.Finaly, friction results from hot ring compression tests and from hot rolling with forward/backward slip measurements are reported. | Y.

| 8 | ATOMISTIC/CONTINUUM SIMULATION OF INTERFACIAL FRACTURE PART Ⅱ:ATOMISTIC/DISLOCATION/CONTINUUM SIMULATION显示文摘Coupled atomistic/dislocation/continuum simulation of interfacialfracture is performed in this paper.The model consists of a nanoscopic core made byatomistic assembly and a surrounding elastic continuum with discrete dislocations.Atomistic dislocations nucleate from the crack tip and move to the continuum layerwhere they glide according to the dislocation dynamics curve.An atoms/continuumoverlapping belt is devised to facilitate the transition between the two scales.Thecontinuum constraint on the atomic assembly is imposed through the mechanics at-mosphere along the overlapping belt.Transmissions of mechanics parameters suchas displacements,stresses,masses and momenta across the belt are realized.Thepresent model allows us to explore interfacial fracture processes under different modemixity.The effect of atomistic zigzag interface on the fracture process is revealed:ithinders dislocation emission from the crack tip,especially under high mode mixity. | 谭鸿来 杨卫 | 1994 | Acta Mechanica Sinica1994，10，3： | 8 |
| 9 | Effect of the Entrained Air Void on Strength and Interfacial Transition Zone of Air-Entrained Mortar显示文摘In order to facilitate the development and application of air entraining agents(AEA) in the high performance concrete, entrained air void structure parameters(air void size range from 10 to 1 600 μm) of 28 d sifted mortar were measured by image analysis method. The relationship between the air void size distribution and strength of mortar was studied by methods of grey connection analysis and multiple linear regression analysis. The multiple linear regression equation was established with a correlation coefficient of 0.966. The weight of the affection of hierarchical porosity on the compressive strength ratio was also obtained. In addition, the effect of air voids on the paste-aggregate interfacial transition zone(ITZ) was analyzed by microhardness. The results show that the correlation between different pore size range and the compressive strength is negative. The effect of air void size distribution on 28 days compressive strength is different: under the condition of similar total porosity, with the increase of the porosity of the air void size, ranging from 10 to 200 μm, and the decrease of the porosity, ranging from 200 to 1 600 μm, the average air void diameter and mean free spacing are decreased; as well as the width of ITZ. On the contrary, the microhardness of the ITZ is increased while the compressive strength loss is decreased. | 高辉 ZHANG Xiong ZHANG Yongjuan | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，5： | 7 |
| 10 | Predicting interfacial thermal resistance by machine learning显示文摘Various factors affect the interfacial thermal resistance(ITR)between two materials,making ITR prediction a high-dimensional mathematical problem.Machine learning is a cost-effective method to address this.Here,we report ITR predictive models based on experimental data.The physical,chemical,and material properties of ITR are categorized into three sets of descriptors,and three algorithms are used for the models.Those descriptors assist the models in reducing the mismatch between predicted and experimental values and reaching high predictive performance of 96%.Over 80,000 material systems composed of 293 materials were inputs for predictions.Among the top-100 high-ITR predictions by the three different algorithms,25 material systems are repeatedly predicted by at least two algorithms.One of the 25 material systems,Bi/Si achieved the ultra-low thermal conductivity in our previous work.We believe that the predicted high-ITR material systems are potential candidates for thermoelectric applications.This study proposed a strategy for material exploration for thermal management by means of machine learning. | Yen-Ju Wu Lei Fang Yibin Xu | 2019 | npj Computational Materials2019，，1： | 7 |

| 12 | Manufacture and characteristics of Al2O3 composite coating on steel substrate by SHS process显示文摘Many steel components are needed to be reinforced on their surface to have a high abrasive resistance and corrosion resistance. Based on self-propagating hightemperature synthesis, a process to making Al2O3 composite coatings on mild steel substrate in atmospheric environment with the help of simple auxiliary facilities was developed successfully. A pre-coated bilayer coating was employed. The effects of Fe content in pre-coated transition layer on phase composition, porosity and interfacial bon ding were studied using scanning electron microscopy (SEM), energy-dispersive spectrum (EDS) and X-ray diffraction (XRD). The thermal shock resistance and abrasive resistance were investigated. When Fe content changes from 0 wt% to 50 wt%, the bond quality at first becomes better and then worse gradually. When Fe content is less 20 wt%, there is a small gap between the transition layer and the substrate;when Fe contents are 30 wt% and 40 wt%, working layer, the transition layer and the substrate bond together well. The working layer is mainly composed of Al2O3, Fe-Cr and Al(Cr)2O3 phases and has a dense structure with porosity of less than 1 %. The coating has a good thermal shock resistance and abrasive resistance. The abrasive resistance of the working layer is about ten times that of the substrate. | Hai-Dong Gao Ze-Hua Wang Jia Shao | 2019 | Rare Metals2019，38，7： | 7 |

| 14 | Interfacial amplification for graphene-based position-sensitive-detectors显示文摘Position-sensitive-detectors(PSDs)based on lateral photoeffect have been widely used in diverse applications1–9,including optical engineering,aerospace and military fields.With increasing demand in long distance,low energy consumption,and weak signal sensing systems,the poor responsivity of conventional PSDs has become a bottleneck limiting their applications,for example,silicon p–n or p–i–n junctions2–5,or other materials and architectures6–10.Herein,we present a high-performance graphene-based PSDs with revolutionary interfacial amplification mechanism.Signal amplification in the order of~10^(4) has been demonstrated by utilizing the ultrahigh mobility of graphene and long lifetime of photo-induced carriers at the interface of SiO_(2)/Si.This would improve the detection limit of Si-based PSDs fromμW to nW level,without sacrificing the spatial resolution and response speed.Such interfacial amplification mechanism is compatible with current Si technology and can be easily extended to other sensing systems11,12. | Wen-Hui Wang Ru-Xia Du Xi-Tao Guo Jie Jiang Wei-Wei Zhao Zhong-Hua Ni Xin-Ran Wang Yu-Meng You Zhen-Hua Ni | 2017 | Light(Science & Applications)2017，6，1： | 6 |
| 15 | Fracture analysis of a functionally graded interfacial zone between two dissimilar homogeneous materials显示文摘In this paper the plane elasticity problem for a functionally graded interfacial zone containing a crack between two dissimilar homogeneous materials has been considered. It is assumed that in the interfacial zone the reciprocal of the shear modulus is a linear function of the coordinate, while Possion’s ratio keeps constant. By utilizing the Fourier transformation technique and the transfer matrix method, the mixed boundary problem is reduced to a system of singular integral equations that are solved numerically. The influences of the geometric parameters and the graded parameter on the stress intensity factors are investigated. The numerical results show that the graded parameters, the thickness of interfacial zone, the crack size and location have significant effects on the stress intensity factors. | CHENG Zhanqi1,2 & ZHONG Zheng1 1.

| 16 | ATOMISTIC/CONTINUUM SIMULATION OF INTERFACIAL FRACTURE——PART Ⅰ: ATOMISTIC SIMULATION显示文摘The phenomenon of interfacial fracture, as manifested by atom-istic cleavage, debonding and dislocation emission, provides a challenge for combinedatomistic-continuum analysis. As a precursor for fully coupled atomistic-continuumsimulation of interfacial fracture, we focus here on the atomistic behavior withina nanoscopic core surrounding the crack tip. The inter-atomic potential under Em-bedded Atom Method is recapitulated to form an essential framework of atomisticsimulation. The calculations are performed for a side-cracked disc configuration un-der a remote K field loading. It is revealed that a critical loading rate defines thebrittle-to-ductile transition of homogeneous materials. We further observe that thenear tip mode mixity dictates the nanoscopic profile near an interfacial crack tip. Azigzag interface structure is simulated which plays a significant role in the dislocationemission from an interfacial crack tip, as will be explored in the second part of thisinvestigation. | 谭鸿来 杨卫 | 1994 | Acta Mechanica Sinica1994，10，2： | 5 |
| 17 | Numerical simulation of the hydrodynamic instability experiments and flow mixing显示文摘Based on the numerical methods of volume of fluid (VOF) and piecewise parabolic method (PPM) and parallel circumstance of Message Passing Interface (MPI),a parallel multi-viscosity-fluid hydrodynamic code MVPPM (Multi-Viscosity-Fluid Piecewise Parabolic Method) is developed and performed to study the hydrodynamic instability and flow mixing. Firstly,the MVPPM code is verified and validated by simulating three instability cases:The first one is a Riemann problem of viscous flow on the shock tube; the second one is the hydrodynamic instability and mixing of gaseous flows under re-shocks; the third one is a half height experiment of interfacial instability,which is conducted on the AWE's shock tube. By comparing the numerical results with experimental data,good agreement is achieved. Then the MVPPM code is applied to simulate the two cases of the interfacial instabilities of jelly models acceler-ated by explosion products of a gaseous explosive mixture (GEM),which are adopted in our experi-ments. The first is implosive dynamic interfacial instability of cylindrical symmetry and mixing. The evolving process of inner and outer interfaces,and the late distribution of mixing mass caused by Rayleigh-Taylor (RT) instability in the center of different radius are given. The second is jelly layer ex-periment which is initialized with one periodic perturbation with different amplitude and wave length. It reveals the complex processes of evolution of interface,and presents the displacement of front face of jelly layer,bubble head and top of spike relative to initial equilibrium position vs. time. The numerical results are in excellent agreement with that experimental images,and show that the amplitude of initial perturbations affects the evolvement of fluid mixing zone (FMZ) growth rate extremely,especially at late times. | BAI JingSong WANG Tao LI Ping ZOU LiYong LIU CangLi | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，12： | 5 |
| 18 | Dynamic anti-plane analysis for two symmetrically interfacial cracks near circular cavity in piezoelectric bi-materials显示文摘The present paper is exposed theoretically to the influence on the dynamic stress intensity factor(DSIF) in the piezoelectric bi-materials model with two symmetrically permeable interfacial cracks near the edges of a circular cavity, subjected to the dynamic incident anti-plane shearing wave(SH-wave). An available theoretical method to dynamic analysis in the related research field is provided. The formulations are based on Green's function method. The DSIFs at the inner and outer tips of the left crack are obtained by solving the boundary value problems with the conjunction and cracksimulation technique. The numerical results are obtained by the FORTRAN language program and plotted to show the influence of the variations of the physical parameters,the structural geometry, and the wave frequencies of incident wave on the dimensionless DSIFs. Comparisons with previous work and between the inner and outer tips are concluded. | A.HASSAN 宋天舒 | 2014 | Applied Mathematics and Mechanics(English Edition)2014，35，10： | 5 |

| 20 | Film condensation heat transfer on a vertical porous-layer coated plate显示文摘Film condensation on a vertical porous coated plate is investigated numerically for a porous/fluid composite system based on the dispersion effect in the porous coating. The mathematical model improves the conventional matching conditions by considering the stress force at the porous coating interface. The numerical results show the effects of the porous coating thickness, the effective thermal conductivity and the permeability on condensate film thickness and local Nusselt number. The predicted average Nusselt number has similar tendencies to experimental results reported in literature, such that using a thin porous coating would be a viable alternative for enhancing the condensation heat transfer. | 马学虎 王补宣 | 1998 | Science China(Technological Sciences)1998，41，2： | 4 |
